I have a complete except engine decalling Mercury Twister 6 banger OPC engine for sale. This early OPC engine has the log type exhaust, Speedmaster MC-1 gearcase, had the green flywheel abd has single barrel carbs which would make it a very early one. Firm price including packaging and shipping is $7,000.00 USD$. Note: I am not open to any other offers or swaps or combos of any other sort of possible offers. That price is the price.
